Terrible customer service from Sylvia

I had a very efficient consultant assigned to me at the beginning of lockdown. For some reason MTN has decided to give me a new consultant who responds after a week, and has not resolved my query from 3 weeks ago. This is so frustrating because I was used to the service I received from Francina Gama which was impeccable. I don’t see why you would assign someone who does not seem to want to work to my case. I’ve contacted Sylvia Hlagala on numerous occasions but to no avail. There was absolutely no reason to reassign the first consultant who takes pride in her work and give me someone who does her job (or rather doesn’t) like she does not want to.
